Applicant's summary and conclusion
- Executive summary:
The water solubility of ZK 90506 was determined at 20 °C with the flask method.
S20 with 95 % confidence intervals: 0.0028 ± 0.0007 g/L (standard deviation s: 0.0009 g/L).
According to the descriptive term in USP (currently USP 28) and EP (currently 5th ed.), the test substance is insoluble in water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
